Using a slick, round poly (like ptp) in the crosses with a shaped poly in the mains can potentially get you better snap-back for the mains, so overall better spin. Also it's sometimes worth using a softer poly in the crosses to counter a harsher poly in the mains (but Cyclone is already pretty soft, so I wouldn't worry about that here).
Personally I think a hybrid with Cyclone mains and poly tour Air crosses would probably be great, since pta is so soft, but I haven't had a chance to try it.
